Many sources of weather, terrain, and fuel data for initialization, assimilation, and verification are freely available through public sites, many in the form of files viewable in Google Earth. Fire ignition tim/location data and imagery of fire extent at later times for specific incidents is still generally in the form of custom datasets where research or suppression teams were available to collect it.

HDF File Information

HDF stands for Hierarchical Data Format, there are two current standards; HDF4 (.hdf extension) and HDF5 (.h5 extension). All of our sources for active fire data and geolocation data use HDF4, though this could change in the future.

Reading HDFs

Matlab uses 'hdfread' to read a dataset into an array, requires filename and the path to the relevant data inside the hdf file. Here's an example call:

fire_mask = hdfread('MOD14.A2016266.1505.006.2016266215413.hdf', '/fire mask')

Where the filename is 'MOD14.A2016266.1505.006.2016266215413.hdf' (more on the naming convention later), and the path inside the hdf to the firemask data is '/fire mask'
